    Hello,
    I accidentally shorted the lighter splitter on the Skoda Octavia 1. It stank and the electricity in the lighter is gone, but the splitter is working. I checked the fuse, but it's good. Where to look for the problem? Replace the cigarette lighter socket or some cube or something else?

    fuse 41 (15A) is definitely good ????

    Yes, I checked with a meter. I was also surprised that this is not it.

    A light bulb, a tester, never a meter :)

    Okay, thanks, I checked them all again calmly and it's the 41. I don't know how it is possible, but it is important that it was clarified.

    But why not a measure?

    Because the meter is lying :)
    Without a load, it will show 12V how the fuse will connect something, and the bulb will not light up anymore :)

    because the meter is very sensitive and can show the transition even on a drooled finger. the light bulb is much more resistant, which makes the measurement more reliable. Of course, the bulb is no more than 3W otherwise you may burn the fuse when checking.

    No. I still remember how a fellow mechanic in ML replaced parts with a few losing stakes. He came and checked the fuses with a meter. I replaced the burned one and the car started moving :)
    From then on, he checks with a light bulb.

    Buddy, wrong. It is the meter that has a large internal resistance - resistance - and when measuring, any conductivity (even burnt fuse remains) is enough to show the transition because it needs a negligible current for measurement - such a burned path is enough. The bulb has a LOW internal resistance and needs very good conductivity to function. Hence, if the fuse is burnt, it connects to some "fern", the meter will show that it is operational and the bulb will show the truth because the necessary current will not flow through such a fuse.

Topic summary

The discussion revolves around a short circuit issue in the cigarette lighter socket of a Skoda Octavia 1, where the user reports a loss of electricity after accidentally shorting the lighter splitter. Despite checking the relevant fuse (41, 15A) and confirming it is intact, the user seeks further troubleshooting advice. Participants suggest checking all fuses thoroughly, as issues can arise from faulty connections or burnt fuses that may not be immediately visible. They emphasize the reliability of using a light bulb for testing over a multimeter, as the latter can give misleading readings due to its high internal resistance. The conversation highlights the importance of ensuring good conductivity in electrical components to diagnose the problem accurately.
